Orchestra Wives (1942)

Connie Ward (Ann Rutherford) is a young woman who on the spur of the moment marries Bill Abbott (George Montgomery), a trumpet player in Gene Morrison's (Glenn Miller) swing band (Miller's character was given a name with initials that matched Miller's so that the band could use their monogrammed stainless-steel bandstands). She soon finds herself at odds with the cattiness and petty jealousies of the other band members' spouses, as they accompany their husbands on their cross-country train tour. Her discomfort is exacerbated by a flirtation between Abbott and Jaynie (Lynn Bari), the band's female vocalist. When Ward eventually walks out on Abbott, their split releases so many other tensions among the musicians and their wives, that leader Morrison is forced to break up the orchestra. Ward and the band's pianist Sinjin (Cesar Romero) then work behind the scenes to reunite the band, which also produces a reconciliation between Ward and Abbott (with additional help from Connie's father (Grant Mitchell)).
